UNITED STATE www Lamer, QF Genemans @Hte SEADE B999F43- eppliatia ne@ Smasher ,2a 1919: serial Np- 32ans i To aZZ'wOm-z't may .connerie Y Be it known that I, LUM-nar, acitizen'of the United-States, residingatConneaut', in the county ofAshtabula andState of Ohio, have invent-ed acertainnew and useful Improvement in Shade Holders,- of

whichthe following is a full, clear, and exact description.

This invention relates to a shade -holder for lamps, and has for its objectyto'providea shade holder-composedof parts which can be quickly assembled. and disassembled to permit the application orf removal of the shade, and which cany be-readilyand inexpensively produced, but at the same timehold's thel shade securelybutyieldingly in position without danger-oi: breakage by mechanical-pressure, or-V by expansion or contraction due to temperature changes.

Thefabove is accomplished by my inven-j tion whichv comprises an annular fixture with a yielding shade engaging member,v alocking ring adapted to be screwed or otherwiseapplied onto the fixture, ltogether with a retaining ring, preferably a split flat ring adaptedto be supported by the locking-ring and' to encircle the'n'eck 'of-the shade, said locking'ring servi-rigato elevate the retaining ringinto clamping engagement with the lixture and atthe salme time to press the ushade against the yield'able member of the fixture.

y "The invention may he further briefly summarized as consisting in certain novel de-` tails "of construction, and combinations and arrangements of o' parts which will be descri-bed inthe specification and set .forth in the appended e-laims.

Inv the accompanying sheet of drawings, Fig. l `is aside -view of a shade holder'embod-ying my invention, parts being in section; Fig. 2 is vazview looking toward theyunder or inner sideA of the annular iixtu're with the other p arts removed; `Fig. 3 iis a viewlooking vat the locking ring with the retaining ringlin position; Fig. 4 -isa ydetail seetionalvi'ew ofthe locking ring; and-Fig. 5 is a plan Viewof the retainingring.

My-invention comprises an annular fixture 10 which emay .have lany conguration, Aand may be designed :to .belsupported on a ceiling, on a wall, or on a rod, chain, or other .device designed to support the lamp. lfhis -xturehas an externally threaded :flange l0?, at the freev fend of which (an unthreaded .eer-tion 1inthe efaskr@ 10"` .Secured 'inv`v the flanged end of the -xture is a yield,-`

`tapered part has a twofold rfuncition my' improved shade holder, I do notregard-itas essential to the invention in its" broader aspects. lThe shade holder includes in addition to the above parts, what may be termed a retaining ringv13, consisting of a flat rirgor'l metall, split or ,divided sfo as to formtwdladjacent ends, one of which is preferably tapered, asshown at 13a. The external diamn eter of this retaining ring is, such that it will rest onthe inturnedilange l2'a of the locking ring, and v wil-l 'be centered thereon by the tapered 'part 12b. 'Ehelinternaldiameter of the retaining ring is such that it *willl encircle .the reduced neckv portion 14ga of the shade 14, the outtur-ned lip orange of the yneck being somewhat smaller in external `diameter than the annular .openingijv ,formed Iby the inturned.flange12?t of the-looking ring;

:In assembling the partsoithe shade holder, the neck ofthe shade is extended np into the locking ring which will then'fhe oil" the ex"- ternally threaded liange of the fixture l0. Then 'the split retaining ring is placed between the out-turned lip on the nek 'of gtlfie shade, and the inturned flange of the locking ringl To do'this the tapered end 18i :is first y inserted downbetween' the shade( andi-the flange of the llocking ring, and theentire ring is then progressively inserted by turn,-

10b of the fixture. This positively stops further movement of the locking ring, and does away with the necessity for any auxiliary fastening device to limit its movement in locking direction. is the locking ring is screwed into place on the fixture, the neck of the shade is pressed against. the yielda-ble member il inside the fixture, and when the locking ring reaches its final position, the globe is pressed firmly butI yieldingly between the retaining ring and the yieldable member ll. All parts are now securely held in position, but without any danger of breakage for it is not possible to screw the locking ring tight-ly enough to cause daiigerons mechanical pressure on the shade, and at the saine time there is suiiicieut give the member ll to allow for expansion contraction., at the same time to ai'- ford for the shade a yielding` abutment which adapts the device admirably for use in conveyances such as street cars, trains, boats and the like, where there may be considerable vibration.

To remove the shade from the other parts, the locking ring is uiiscrewed, and with a suitable tool, such as the blade of a knife, or any other convenient. instrument., the tapered end of t-he retaining ring is li ted above the flange on the neck ofthe shade, the tapered neck of the locking ring affording a. sufficient space to enable the. retaining ring to be sprung outwardly to this extent. Then by running the blade or tool progressively around the retaining ring, from the beveled end to the other end. the retaining ringr gradually lifted from between the neck of the shade and the locking ring, whereupon the shade can he lowered frein the locking ring. L'

In its simplicity and effectiveness the shade holder embodying iny invention is marked iiiprovement over devices which have been used heretofore, and especially those utilizing a. retaining` member in the form of an endlessl coil spring, the use of which requires a special Vlocking` device to stop the movement of the locking ring to prevent breakage of the shade. i,

ln the drawings i have illustrated the preferred construction, which may be inedified somewhat, without departing from the principal. features of the invention.. For

example, the yield'able shade engaging enember ll is an important feature of the construction when the lamp embodying `he iiivention is used on conveyances such as cars. trains and boats, in other words. wherever the lamp is subjected to vibration,y but this feature could be eliminated where the lamp is used under circumstances suoli that vi bration is absent. Furthermore, while one end of the retaining ring 13 is preferably tapered, as before stated,the tapered feature of this ring might be eliminated, though its provision adds materially to the ease with' which the. parts can be assembled or dis assembled. y l

Having described my invention, l claim:

l. A shade holder comprising an annulai fixture, a locking ring adapted to be posi tioned thereon, and a retaining member loosely encircling the neck of the shade and. rigidly clamped in said loosely encircling position between opposing parts of the fixture and locking ring.
